+# Voltage Divider
+
+## Simple Voltage Divider
+
+This is sort of unrealistic because there is no current flowing out of the voltage divider on the right side:
+
+![Voltage Divider](./voltage-divider.svg)
+
+#### Equation
+
+$$
+\begin{flalign}
+Vout & =\text{Vin }x*(\frac{R2}{R1+R2})&\\
+\end{flalign}
+$$
+
+## Voltage Divider with Load
+
+When the output of the voltage divider is connected to something the current drops on the output, as that something uses some of it.
+
+![Voltage Divider](./voltage-divider-load.svg)
+
+The load is connected in parallel to R2, so we can calculate it as a parallel resistor.
+
+The new Equation:
+
+$$
+\begin{flalign}
+Vout & =\text{Vin }x*(\frac{R2 || RL}{R1+R2 || RL})&\\
+\end{flalign}
+$$
+
+### Example
+
+Lets calculate the current in this circuit:
+
+![Voltage Divider Load Example](./voltage-divider-load-example.svg)
+
+1. We calculate the Resistance in the subcircuit (R2 and RL) as they are connected in parallel which means
+
+$$
+\begin{align}
+\frac{1}{Re}&=\frac{1}{R2}+\frac{1}{RL} &\textit{Replace Variables}\\
+\frac{1}{Re}&=\frac{1}{100}+\frac{1}{150} &\textit{Add Fractions}\\
+\frac{1}{Re}&=\frac{1}{60} &\textit{* Re}\\
+1&=\frac{Re}{60} &\textit{* 60}\\
+60&=Re \\
+\end{align}
+$$
+
+The simplified circuit now looks like this;
+
+![Voltage Divider Load Example](./voltage-divider-load-example-2.svg)
+
+Now we can easily calculate the Resistance in the circuit
+
+With the resistance we can now calculate the current  inside the load circuit by using the simple voltage divider equation:
+
+$$
+\begin{flalign}
+Vout &=\text{Vin }x*(\frac{Re}{R1+Re})&\\
+Vout &=5*(\frac{60}{100+60})&\\
+Vout &=5*(\frac{60}{100+60})&\\
+Vout &=1.875v
+\end{flalign}
+$$
